TECHNICAL FIELD

Aspects of the present disclosure relate to systems and methods for providing internal support for an air mattress.

BACKGROUND

Inflatable air mattresses are often filled with air, and when a load is set atop an air mattress, such as a user sitting or lying on the air mattress, the load can cause an increase in the internal pressure of the air mattress. In turn, such an increase in internal pressure can cause the air mattress to deform or distort in shape, such as by causing the walls of the air mattress to bow outwards or cause the body of the air mattress to shear and slant in one or more directions. Such distortions can create a sense of imbalance that can affect a user's comfort level when, for example, attempting to sleep on the inflated air mattress. Accordingly, to increase structural stability, some air mattress designs include internal structures attempting to inhibit such distortions. Some inflatable air mattresses may include an internal support system that includes one or more separate chambers. However, including multiple chambers can increase the time associated with inflating or deflating the air mattress. Some inflatable air mattresses may attempt to solve this problem by including apertures in some of the components of the internal structure, such as a mesh material, for example. But the use of mesh material can cause difficulties during manufacturing, such as attaching the mesh material to other portions of the air mattress.

Thus, it would be desirable to develop an improved internal support structure for preventing the distortion of the shape of the inflated air mattress when in use.

The materials described hereinafter as making up the various elements of the examples of the present disclosure are intended to be illustrative and not restrictive. Many suitable materials that would perform the same or a similar function as the materials described herein are intended to be embraced within the scope of the example embodiments. Such other materials not described herein can include, but are not limited to, materials that are developed after the time of the development of the invention, for example.

Examples of the disclosed technology include an inflatable air mattress having an internal support system for providing structural stability to the air mattress. In various examples, an inflatable air mattress having an internal support system can include one or more loops of material, and each loop of material can be attached to a top panel and a bottom panel of the air mattress. According to some examples, the internal support structure described herein can prevent distortions in the shape or orientation of the air mattress and add stability and support to the structure of the air mattress.

Throughout this disclosure, certain examples are described in exemplary fashion in relation to an inflatable air mattress. However, examples of the disclosed technology are not so limited. In some examples, the disclosed technique can be effective in other inflatable products such as inflatable pillows or inflatable supports.

Referring now to the drawings, FIGS. 1 and 2 illustrate an inflatable air mattress 100 having a top panel 102, a bottom panel 104, and one or more side panels 106 to form an airtight enclosure. The top panel 102, bottom panel 104, and one or more side panels 106 can be made of polypropylene, polyethylene, nylon, polyvinyl chloride (“PVC”), polytetrafluoroethylene (“PTFE”), plastic, rubber, or any other suitable material that is known in the art. The inflatable air mattress can be filled with air (or any gas) and used as a mattress, a pillow, or a cushion, for example. The inflatable air mattress 100 can include a valve through which air can be pumped into the internal chamber of the air mattress 100 or can be released from the internal chamber of the air mattress 100.

The inflatable air mattress 100 can include multiple internal support structures 110. The internal support structures 110 can extend across some of all of the width or length of the inflatable air mattress 100. For example, as shown in FIG. 1, the internal support structures 110 can extend across substantially all of the width or length of the air mattress 100. As shown in FIG. 2, the internal support structures 110 can have a width that is substantially less than the width or length of the air mattress 100. The air mattress 100 can include one or more internal support structures 110 of a first size (e.g., having a width that is substantially the same distance as the width or length of the air mattress 100) and one or more internal support structures 110 of a second size (e.g., having a width that is substantially smaller distance than the width or length of the air mattress). One or more internal support structures 110 can be positioned substantially parallel to the width or length of the air mattress 100 (e.g., parallel to one or more side panels 106). Additionally or alternatively, one or more internal support structures 110 can be positioned diagonally with respect to the width or length of the air mattress 100 (e.g., parallel to one or more side panels 106). Additionally or alternatively, one or more internal support structures 110 can be positioned diagonally with respect to one or more side walls 106.

As shown more clearly in FIGS. 3 and 4, each internal support structure 110 can include a length of material that is wrapped in a loop 312. The loop 312 can be made from any suitable material, such as made of polypropylene, polyethylene, nylon, PVC, PTFE, plastic, or rubber, for example. The loop can be made from a material having apertures. For example, the loop 312 can made using a mesh material. Each internal support structure 110 can be attached to the top panel 102 and the bottom panel 104. Alternatively or in addition, one or more internal support structures 110 can be affixed to the internal surface of either the top panel 102 or bottom panel 104 by an attachment strip 314. An attachment strip 314 can be a piece of material (e.g., polypropylene, polyethylene, nylon, PVC, PTFE, plastic, rubber) that can be welded, glued, adhered, or otherwise attached to the internal surface of the top panel 102 or bottom panel 104 to secure a portion of the attachment strip 314 to the top panel 102 or bottom panel 104. A portion of the internal support structure 110 can be attached to one or more internal surfaces of a side panel 106, a portion of the internal support structure 110 can be attached to one or more adjacent internal support structures 110, and/or a portion of the internal support structure 110 can be attached to a side panel 106. For example, a portion of the internal support structure 110 can be attached to one or more adjacent internal support structures 110 and another portion of the internal support structure 110 can be attached to a side panel 106.

The loop 312 can have two ends that overlap one another. As shown in FIG. 3, an attachment strip or side strip 316 can be positioned proximate the overlapping ends of the loop 312. The side strip 316 can be a piece of material (e.g., polypropylene, polyethylene, nylon, PVC, PTFE, plastic, rubber). Alternatively, the side strip 316 can be the same material as the attachment strips 314. In other examples, the overlapping ends of the loop 312 can be welded, glued, adhered, or otherwise attached to the side strip 316.

The disclosed technology can include a loop 312 having two attachment strips 314 positioned within the loop 312 to affix the loop 312 to a top panel and a bottom panel 104, as well as one side strip 316 to secure the overlapping ends of the loop 312 to one another. The side strip 316 can be positioned outside the loop 312 and adjacent to the overlapping ends of the loop 312, the side strip 316 can be positioned within the loop 312 and adjacent to the overlapping ends of the loop 312, and/or the side strip 316 can be positioned between the overlapping ends of the loop 312.

The disclosed technology can include a second side strip 316. For example, a first side strip 316 can be positioned outside the loop 312 and adjacent the overlapping ends of the loop 312, and a second side strip can be positioned within the loop 312 and adjacent to the overlapping ends of the loop 312, as well as adjacent to the first side strip 316. That is, the overlapping ends of the loop 312 can be sandwiched between two side strips 316, and the two side strips 316 can be welded, glued, adhered, or otherwise attached one another such that the overlapping ends are secured.

In some examples, a side strip 316 may not be included. Instead, the overlapping ends of the loop 312 can be positioned proximate the top panel 102 or the bottom panel 104 such that an attachment strip 314 can simultaneously affix the loop 312 to the top or bottom panel 102, 104 and secure the overlapping ends of the loop 312 to one another. For example, an attachment strip 314 can be positioned within the loop 312 and adjacent to the overlapping ends of the loop 312, as well as adjacent to the top or bottom panel 102, 104. Alternatively or in addition, an attachment strip 314 can be positioned between the overlapping ends of the loop 312 and adjacent to the top or bottom panel 102, 104. Regardless of configuration (i.e., the attachment strip 314 being positioned within the loop 312 or between the overlapping ends of the loop 312), a second attachment strip 314 can be positioned within the loop 312 and opposite the first attachment strip 314 that is securing the overlapping ends of the loop 312 together such the second attachment strip 314 can secure the loop 312 to the top or bottom panel 102, 104 (i.e., the panel opposite the panel to which the first attachment strip 314 is securing the loop 312). Internal support structures 110 omitting a side strip 316 can be more difficult to manufacture as compared to internal support structures 110 including one or more side strips 316, but internal support structures 110 omitting a side strip 316 can enable an air mattress 100 to be constructed using less material.

Referring to FIG. 4, an internal support structure 110 can include two side strips 316. A portion of the loop 312 opposite the overlapping ends of the loop 312 can also be welded, glued, adhered, or otherwise attached to the side strip 316, which can cause the loop 312 to “pinch” together at the attachment point to the side strip 316 (i.e., the width of the loop 312 can decrease at or near the location that the loop 312 is attached to the side strip 316). A first side strip 316 can be positioned outside the loop 312 and adjacent the overlapping ends of the loop 312, and a second side strip 316 can be positioned outside the loop 312 and adjacent a portion of the loop 312 opposite the overlapping ends of the loop 312. Alternatively or in addition, a first side strip 316 can be positioned between the overlapping ends of the loop 312, and a second side strip 316 can be positioned outside the loop 312 and adjacent to a portion of the loop 312 opposite the overlapping ends of the loop 312. Regardless, the first and second side strips 316 can be welded, glued, adhered, or otherwise attached to one another, which can cause the overlapping ends of the loop to become secured together and can cause the width of the loop 312 to “pinch” together at or near the location of the first and second side strips 316.

An internal support structure 110 can “pinch” together while including only a single side strip 316. In some examples, the side strip 316 can be positioned outside the loop 312 and adjacent to the overlapping ends of the loop. The side strip 316 can be positioned outside the loop 312 and adjacent to a portion of the loop 312 opposite the overlapping ends of the loop 312. The side strip 316 can be positioned between the overlapping ends of the loop 312. Regardless, each of the overlapping ends, the portion of the loop 312 opposite the overlapping ends, and the side strip 316 can be welded, glued, adhered, or otherwise attached together.

The loop 312 can be made from a material that can be welded, glued, adhered, or otherwise attached to itself and/or welded, glued, adhered, or otherwise attached to the top panel 102, bottom panel 104, and/or side panel 106. Thus, an internal support structure 110 may not include an attachment strip 314 or a side strip 316 but can still be affixed to the top panel 102, bottom panel 104, side panel 106, and/or an adjacent internal support structure 110. Similarly, the overlapping ends of the loop can be secured directly to one another (i.e., without an attachment strip 314 or a side strip 316) by welding, gluing, adhering, or otherwise attaching the overlapping ends together. As will be appreciated, a “pinch” can be created by welding, gluing, adhering, or otherwise attaching the overlapping ends to a portion of the loop 312 opposite the overlapping ends.

FIGS. 5-12 depict various examples of the disclosed technology. For example, FIGS. 5-8 depict an air mattress 100 including five internal support structures 110 that extend along a large portion of the length of the air mattress 100. The disclosed technology (such as the example air mattress shown in FIGS. 5-8 and as most clearly shown in FIGS. 7 and 8) can include a first side strip 316 that can be positioned outside the loop 312 and proximate the overlapping ends of the loop 312, and a second side strip 316 that can be positioned within the loop 312 and proximate the overlapping ends. The first and second side strips 316 can then be welded, glued, adhered, or otherwise attached to one another, causing the overlapping ends to close the loop.

FIGS. 9-12 depict an air cushion representative of an air mattress, in accordance with some examples of the disclosed technology. The example air cushion depicted includes a single internal support structure 110, which includes a first side strip 316 positioned outside the loop 312 and proximate the overlapping ends and a second side strip 316 a second side strip 316 can be positioned outside the loop 312 and adjacent a portion of the loop 312 opposite the overlapping ends of the loop 312, as discussed above. As shown most clearly in FIGS. 11 and 12, attachment of the first side strip 316 to the second side strip 316 causes the loop 312 to “pinch” together at or near the first and second side strips 316. Though only a single support structure 110 is shown, it is understood that a plurality of similar support structures 100 could be used in an air mattress, according to the disclosed technology.
